Abstract
A sense amplifier circuit for single-ended data characterized by the responsiveness of the reference voltage to variations in processing parameters and tolerance for noise. Matching of the dataline voltage to the reference voltage enables the comparison of data with the reference to operate with greater accuracy. Isolation of the reference voltage preserves its integrity as a high logic state from subsequent variations in the dataline.
